Ingredients Needed

• 2 cups cooked chicken breast (shredded or cubed)
• 3 cups fresh broccoli florets (cut into bite-sized pieces)
• 1 cup heavy whipping cream
• 4 oz cream cheese (softened)
• 3/4 cup grated Parmesan cheese
• 1 cup shredded mozzarella cheese (divided)
• 2 cloves garlic (minced)
• 1 tablespoon olive oil or butter
• 1/2 teaspoon Italian seasoning
• Salt and black pepper to taste
• Fresh chopped parsley (for garnish)

How to Make Our Keto Broccoli Chicken Alfredo Casserole

1. Preheat your oven to 375°F (190°C) and lightly grease an 8×11-inch baking dish with olive oil or cooking spray.
2. Steam the broccoli florets for 2–3 minutes until they are bright green and slightly tender but still crisp. Drain well to avoid any watery sauce.
3. Sauté the minced garlic in a saucepan with butter or olive oil over medium heat for about 1 minute until fragrant.
4. Whisk in the heavy whipping cream and softened cream cheese. Simmer gently until the cream cheese melts completely and the sauce begins to bubble. Turn off the heat and stir in the Parmesan cheese, Italian seasoning, salt, and pepper until perfectly smooth.
5. Combine the cooked chicken pieces and steamed broccoli in your prepared baking dish. Pour the warm alfredo sauce evenly over the top, tossing gently to coat.
6. Top the entire mixture with the shredded mozzarella cheese.
7. Bake for 20 minutes, or until the sauce is bubbling around the edges and the cheese on top is completely melted. Broil for the final 2 minutes for a beautiful golden-brown crust.
8. Garnish with fresh parsley before serving up these delicious macro-friendly meals.

Storage & Serving Suggestions

• Storing: Keep any leftovers in an airtight container in the refrigerator for up to 3 to 4 days. It actually tastes even better the next day as the flavors meld together!
• Reheating: Warm individual portions in the microwave on medium power, or place the casserole back into the oven at 350°F for 10–12 minutes until heated through.
• Freezing: This casserole freezes beautifully. Assemble the dish entirely but skip the final baking step. Wrap it tightly with plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw completely in the fridge before baking.
• Serving pairings: Keep it strictly low-carb by serving this alongside a crisp caesar salad (sans croutons) or some garlic-rubbed grilled zucchini ribbons.

Tips & FAQs (SEO-Optimized)

Can I use frozen broccoli instead of fresh?

Yes, frozen broccoli works well for meal prep recipes. Just make sure to thaw it completely and squeeze out all excess moisture with a paper towel before adding it to the dish, otherwise, your Alfredo sauce will turn out watery.

What can I use instead of chicken?

This recipe is incredibly versatile. You can easily swap the chicken for leftover holiday ham, browned smoked sausage slices, or even juicy sautéed shrimp to keep your weight loss meals exciting and varied.

Why did my Alfredo sauce separate or turn grainy?

Dairy sauces can separate if they are heated too quickly on high heat. Always melt your cheeses over medium-low heat and remove the pan from the burner as soon as you stir in the Parmesan cheese to ensure a silky-smooth texture.

Is this suitable for a standard meal prep routine?

Absolutely. This is one of those simple meals that reheats incredibly well for lunches throughout the week. The broccoli stays structurally sound, and the fats in the sauce keep the chicken moist.
